Procedure

The category name must be unique to the currently-selected vCenter Server system.

Description

You can provide text in the description to describe the purpose or usage of the category.

Cardinality

Select 1 tag per object to allow only one tag from this category to be applied to an object at any one time.

Use this option for categories whose tags are mutually exclusive. For example, a category called Priority with tags High, Medium, and Low should allow one tag per object, because an object should have only one priority.

Select Many tags per object to allow multiple tags from the category to be applied to an object at any one time.

Use this option for categories whose tags are not mutually exclusive.

After you have set the cardinality of a category, you can change the cardinality from 1 tag per object to Many tags per object, but not from Many tags per object to 1 tag per object.

Associable Object Types

Select whether tags in this category can be assigned to all objects or only to a specific type of managed object, such as virtual machines or datastores.

After you have set the associable object types for a category, you can change a category that is associable with a single object type to be associable with all object types, but you cannot restrict a category that is associable to all object types to being associable to a single object type.
